等离子喷涂参数对Al_2O_3-13wt%TiO_2涂层组织及硬度的影响
|
摘要
采用大气等离子喷涂技术(APS)和正交试验法优化Q235钢基体上的微米Al_2O_3-13wt%TiO_2涂层。借助扫描电镜、X射线衍射仪、划痕测试仪和显微硬度计对涂层进行了分析。结果表明:优化后该涂层组织结构致密,无明显裂纹。优化后涂层的附着力平均值为85.9 N,平均硬度为1133 HV。
By air plasma spraying(APS), the micron Al_2O_3-13wt%TiO_2 coating on Q235 steel surface was optimized. The coating was analyzed by scanning electron microscopy, X ray diffraction, scratch tester and microhardness tester. The results show that after optimization, the microstructure of the coating is compact, which has no obvious crack. The average value of adhesion force of the optimized Al_2O-3-13wt%TiO_2 coating is 85.9 N, and the average hardness at the same section depth is 1133 HV, which indicates that the optimized coating has better performance.
